Before you start developing applications on MapR’s Converged Data Platform, consider how you will get the data onto the platform, the format it will be stored in, the type of processing or modeling that is required, and how the data will be accessed.

A MapR Ecosystem Pack (MEP) provides a set of ecosystem components that work together on one or more MapR cluster versions. Only one version of each ecosystem component is available in each MEP. For example, only one version of Hive and one version of Spark is supported in a MEP.

MapR supports public APIs for MapR-FS, MapR-DB, and MapR-ES. These APIs are available for application development purposes.

Installing the Hive-on-Tez User Interface

This topic describes installation of the Hive-on-Tez user interface by using the MapR
Installer or manual steps.

Installation Using the MapR Installer

When you use the MapR Installer to install Tez, the timeline server for the Hive-on-Tez
user interface is installed automatically. If the Enable MapR Secure
Cluster option is enabled in the MapR Installer, the timeline server is
installed to be secure.

The Tomcat server is installed into this
folder:

/opt/mapr/tomcat/apache-tomcat-<version>

To start using the Hive-on-Tez user interface if the Enable MapR Secure
Cluster option is enabled or if the cluster is Kerberized, you must log in to
the timeline server user interface:
